Science of the Saints, 5 August, Saint Eusignius

The Martyr Eusignius was born at Antioch in the mid Third Century. Over the course of sixty years he served in the Roman armies of the emperors Diocletian, Maximian Hercules, Constantius Chlorus, Constantine the Great and his sons.

Saint Eusignius was a companion of Saint Basiliscus (Comm. 3 March and 22 May), and he provided an account of his deed of martyrdom (+ c. 308). 

At the beginning of the reign of Saint Constantine the Great, Saint Eusignius was a witness to the appearance in the sky of the starry Cross, a prediction of victory. 

Saint Eusignius retired in his old age from military service and returned to his own country. There he spent his time in prayer, fasting, and attending the temple of God. And thus he lived until the reign of Julian the Apostate (361-363), who yearned for a return to paganism. 

Through the denunciation of one of the Antioch citizens, Saint Eusignius stood trial as a Christian before the emperor Julian in the year 362. He fearlessly accused the emperor of apostacy from Christ, and reproached him with the example of his relative, Constantine the Great, and he described in detail how he himself had been an eyewitness to the appearance in the sky of the sign of the Cross. Julian did not spare the quite old Saint Eusignius, then 110 years old, but rather ordered him beheaded.
